Attached is a picture from my coworkers new Water Furnace Envision NDV028 unit operating at full capacity. He took some measurements after installation and found that the unit was always 20-30%...

Thanks everyone.

Spoke with the city inspector this morning and he is going to call the contractor and advise him to get a permit so that the inspector can inspect it. A kinda round about way of...

Natural Gas. The load is: Furnace (oversized) 100k btu, gas logs 38k btu, 40 gal gas water heater 35k btu? haven't looked recently on the water heater.



I am starting to like gastite less and...

No bonding. I take it connecting it to CIP coming in from the meter does not count?

Water is city water and not hard. Very neutral as most water systems go.

Forgot a piece or two of information. The total load on the gas line is about 170000 BTU. Don't know if this helps but can't hurt.

My parents had to have foundation work done to correct a problem that was created by a waterproofer's improper backfill. The Fixing company needed the gas line moved since it ran up against the wall...

Call or send an Email to Waterfurnace. They seem to have good customer relations. I sent them an email before I talked to any contractors and the regional Distributor called and then corporate...

With stream water you also have to be carefull of sediment runoff, ie muddy water when it rains.

I would recomend a horizontal CLOSED loop since you have a hign water table. My loop was burried...

CPH is a variable in the PID loop equation (aka transfer equation) that resides in the stat memory. A PID equation is an equation that looks at the set point, how far from the setpoint you are, how...

If you think you may have varing load conditions, like entertaining guests vs one or two people you may want to consider a two stage AC or heat pump since the heat load/loss seems fairly low.

Right now the Waterfurnace has the most effecient unit available, the Envision. But, this will probaly shift back to Climate Master when they introduce a new model.

I have heard some installer...

Just found out my waterfurnace has a dip switch to disable aux strip heat. According to the manual full "emergency heat" is still available when "aux" heat is disabled.

the other option is not to...

one: your water will have antifreeze in it.
B: if it is that cold to freeze your water your pump will be running.

So the chances of your short outside pipes freexing are very low. A power...

Don't forget the Feds give you a 30% tax credit with no limit for geo units as well. Your state may have additional incentives. Just remember that electric prices are going to go up and up and up...

The breaker for my strip heat also power the blower and electronics. I have been thinkin of the switch Idea. I would think that the Tranquility 27 is advanced enough, like my envision, that if a...

My envision has a leaky air coil as well. But I have a ten year warranty. Yes I am disappointed that this has happened. My installer did mention that the replacement coils are noticably heavier...

I agree it is not free but at a COP of 5 it is a lot cheaper than the electric elements in the WH. But it still produces far more hot water in the winter than the summer. According to my contractor...

My desuperheater makes more hot water in the winter becasue I have not only longer run times but quality of the heat from the discharge of the compressor is a much much higher (ie higher temp). In...

If they don't install what is on the quote/contract you don't pay what is on the quote/contract.

My installer had a unit right before mine that had two compressor failures, air coil failure with the air coil failing in between the two compressors I think. Anyway WF replaced the Premiere E unit...

I get far more hot water off of my Waterfurnace in the winter than the summer. According to the contractor who installed it that is normal for R410 systems and oppisite form R22 sytems. Which if...

Tetco is still in business. Ten tons does seem to be excessive for the size of your house. Did someone recomend this equipment to you?

liquid water expands as the temperature increases from 0C to 100C. Water Vapor expands as temp increases as well. The funny thing about liquid water is what happens as the temp decreases past 0C...

1. As would be all sewer piping.
2. If you are worried about legionella I would suggest never using PEX pipe. The HX is copper and copper has intrinsic antibacterial and antimicrobial properties....
